(2) Plate supply devices 100 and 200 The plate supply devices 100 and 200 are basically configured the same. Therefore, in the following description, only the plate feeding device 100 will be described.

FIG. 4 shows a schematic configuration diagram of an embodiment of the plate supply device ioo, in which the plate feeder ioo is a front view thereof, (a) is its 11th view, and (C) is a perspective view of the plate. In the figure, Various kinds of plates 5 are sorted and accommodated from the upper openings of the hoppers IIA and 1113.IIC of the hopper section 11.In addition, in this embodiment, the hoppers IIA and 1113.
K accommodates a wide and shaped plate, the hopper IIB accommodates a wide rectangular plate, and the hopper 11C accommodates a narrow plate. The plate feeding device 100 includes this hopper section 11 (hopper IIA, 1113.xxc), and is composed of a pusher drive mechanism 123 and a plate delivery mechanism 124 arranged on the bottom side of this hopper section 11. The button mechanism 123 includes a button 125, a button frame 126, a rack 127 fixed to the button mounting frame 12G, and a drive motor 1 that meshes with the rack.
It consists of a pinion 128 that transmits the driving force of 29 to the brush 1i'' 125, a photosensor 130, 131, etc. that detects the position of the bushing 125.
The lower surface 13 includes an upper surface 132 and a lower surface 133 having a step A corresponding to the thickness of 501 plates.
Play 1- on 3. 5 is placed. Butsusha mounting frame 1
26 fixes the bushing 25 to the upper end and connects the drive motor 1.
29, the gear driven by the pinion 128 and the rack 127 is guided by the fixed frame 134 via the ball bearing 135, and reciprocates linearly. Furthermore, light shielding plates 136 and 137 are fixed to the gripper mounting frame 126. The continuous light plate 136 blocks light from the first sensor 130 to detect the reversal position of the bushing 1250, and the light shielding plate 137 blocks light from the photosensor 131 to detect the bush l 25 (r) starting position.

Next, the plate feeding mechanism 124 and the pusher 125
The drive motor 138 is provided near the maximum protrusion position of the
It consists of a rubber roller 139 that is rotationally driven by a rubber roller 139 and a presser row 2140 that is provided opposite to the rubber roller 139. One end of the spring 141 is fixed to the hopper frame 146, and the other end applies a pressing force to the presser roller 140 against the rubber roller 139.

Chiru.

The functions of the plate supply device configured as described above will be explained.

The bushing 125 moves in the direction of the arrow X due to the linear motion driven by the drive motor 129 and transmitted via the pinion 128 and the rack 129. similarly tries to move, but is blocked by the gate plate 142. However, between this gate plate 142 and the lower surface 133 of the buttonhole 125, there is a gap j3 that is slightly larger than the width of 501 plates. After the plate 5 is pushed out by the bushing 125, it is sent to the marking conveyor 13 of the plate conveying device 300 by the rubber roller 139 and the presser roller 140. The bushing 125 starts. In this case, the position of the step A between the upper step surface 132 and the lower step surface 133 is at the rear of the plate 5, and there is a gap W.

The existence of this gap W is desirable in order to lower the starting l/luke of the drive motor 129, and is usually about Lmm to 5 I
It is set to about n7rL. Further, by configuring the drive motor 129 to stop naturally when pushing out the crusher 125 in the arrow direction However, due to the natural stop, the bushing 125 may overrun.Therefore, the light shielding plate x36t4y(
It is formed longer by the amount of overrun. In addition, in order to check whether the button 125 is stopped at a position suitable for starting, the light shielding plate 137 operates the starting position sensor 131 when the button is in the starting position. By confirming that both sensors 130 and 131 are operating simultaneously, the position of the bushing 125 can be confirmed.

Next, FIG. 5 shows an explanatory diagram of the button operation state, and (A)
( is in a normal pusher state, (B) is in a pusher state with a gap, (Q is in a defective pusher state, and (D) is in a state where the gap has been removed. In the figure, the parts that have the same functions as those in Figure 4 are: The same reference numerals are given.As shown in Figure 1, the plate 5 is not necessarily in the normal state in which it is pushed by the step part A of the bushing 1250 and is ejected in the gap W-00. Figure (B) shows - jJ: Sea urchins may be carried by the intense friction between the plate 5 and the lower surface 133 and protrude with the gap W remaining.In this case, as shown in Figure (C) As the pusher 125 advances as shown in FIG.
It may get stuck between the bushing and the lower surface 133 of the bushing 125, making it impossible to continue operation. In order to avoid this, in the plate feeding mechanism 124, the rubber roller 1390 is stopped from rotating and has the role of a stopper to prevent the pusher 125 from advancing as shown in ] in the same figure, so that the gap W becomes zero. After that, the rubber row 2139 is rotated by the drive motor 138, and the plate 5 is sent out.

At the same time, the photo sensor 130 detecting this position causes the drive gear 129 to rotate in the opposite direction, inverting the bushing 125 and returning it to the starting position.

At the time of this return, the photosensor 130 is shielded from light by the light shielding plate 136, and the photosensor 131 is shielded from light by the light shielding plate 137.
If the light is not blocked by the button switch 143, the push button switch 143 will not return to the starting position.
The bushing 125 is returned to its original state.

IL Plate Transport Apparatus 300, 400 The plate transport apparatuses 300 and 400 are basically configured in the same way. Therefore, in the following description, only the plate conveying device 300 will be described.

FIG. 6 shows a schematic configuration diagram of an embodiment of the plate conveying device 300, where Q is a front view thereof and (Bl is a plan view thereof. In the plate conveying device 300, the hopper section 11 of the plate feeding device 100 is Plays 1-5 (wide plays 5A, still narrow plays 1 and 5B) are selected and sent. This plate conveyance device 300 is mainly composed of a conveyor belt 13, a fixed guide support 323, a stopper 324, a proximity switch 325, a plate length detection sensor 326, a plate width detection sensor 327, and a floating guide 328.Conveyor belt 13 In this embodiment, three rubber timing belts 329, a driving roller 330, a driven roller 331, and a presser roller 332, 333 are used.
, an intermediate roller 334, a drive motor 335, and the like. The fixed guide side plate 323 has these three timing bells! -329, and guides the wide plate 5A being conveyed.

The stopper 324 is provided between the fixed guide fnil plates 323, protrudes downward from the surface of the timing bell l-329, and stops the wide grating 5A at the stamping position (marking position S+ in FIG. 3) with a stopper bar 336; Solenoid 337 that lowers this stopper bar 336, stopper bar 3
36 and a solenoid 337, and a spring 339 interposed between the stopper rod 336 and the solenoid 337. In addition, the proximity switch 325

Next, the functions of the grate conveying device 3000 having the above-described configuration will be explained. The wide plate (5A) protruding from the hopper section 11 of the plate feeding device 100 is a guide side plate 323.
It is guided by the timing belt 329 and is brought into contact with a stopper rod 336 protruding from the surface of the timing belt 329 to stop. At the same time, wide play 1-
When the center of the tip of the 5A enters directly under the proximity switch 325, the proximity switch 325 operates to stop the belt drive motor 335. In addition, this drive motor 335
When the timing belt 329 suddenly stops, the timing belt 329 returns,
(Wide play) There is a risk that the stopping position of 5A may change.

For this reason, the drive motor 335 gradually comes to a natural stop.

Therefore, the stopper rod 336 is rotatably supported at the tip of the solenoid 337 by a pin 338. Spring 339 generates a vertical support force for stopper bar 336 . The plate length detection sensor 326 and the plate width detection sensor 327 detect two types of wide plates 5A (i.e., 5AL, 5AL,
5AS) has completed the import.

When the marking is completed and an unloading command is received, the drive motor 335
is driven again, and at the same time, the solenoid 337 is activated, the stopper rod 336 is pulled down, and the wide plate 5A is carried out from the plate transport device 300.

Next, Fig. 7 shows a schematic configuration diagram of the floating guide in Fig. 6, (4) is its front view, (13) is the state when the narrow plate is brought in, and C) is the state when the narrow plate is taken out. It is. In the figure, the parts having the same functions as in Figure 6 include:
The same reference numerals are given. The floating guide 328 has a concave cross-sectional shape and includes a guide part 340 that guides the narrow plate 5B on both sides, and a stopper part 341 provided inside the guide part 340 and formed narrowly. When carrying in the narrow plate 5B as shown in the figure or (B), the floating guide 328 is
It floats up to a state of 328B, and then descends to a state of 328B when carrying out the narrow plate 5B as shown in FIG. Furthermore, when carrying in and out the wide grate 5A, the floating guide 328 descends from the surface of the timing belt 3290 as shown in FIG. As described above, in this embodiment, the elevating mechanism for elevating and lowering the floating guide 328 includes a forward/reverse drive motor 342, a pulley 343 to which the rotation of this drive motor 342 is transmitted, a drive link 344 that rotates due to the rotation of this pulley 343, and It consists of a driven link 345 and the like.

With the above-mentioned configuration, when carrying in and out of the wide plate 5, the floating guide 328, which had been lowered from the surface of the timing belt 3290, receives the command to carry in the narrow plate 5B and moves as shown in CB in the same figure. The state will be 328A, which is the maximum floating position. The narrow plate 5B is connected to this floating guide 328.
It is guided by the timing belt 329 in the center and carried in! - It comes into contact with the collar portion 341 and stops. At this time, the tip of the narrow plate 5B enters directly under the proximity switch 325 shown in FIG. 6, and the proximity switch 325 is activated to stop the belt 1 drive motor 335 and stop the timing belt 329 from being carried in.

After the marking is completed, in response to an unloading command, the floating guide 328B is in a lowered state at an intermediate position, as shown in FIG. At this intermediate position, the stoppage by the stopper portion 341 during carrying in the narrow gray plate 5B is released, and the timing belt 329 starts carrying out the movement, and the narrow plate 5B is carried out.

In addition, when the wide play) 5A is carried in, the floating guide 328 further descends from the state of the floating guide 328B and is brought to a completely downward position from the surface of the timing belt 329, and the wide play) 5A Do not interfere with the loading and unloading of items.

(2) Plate unloading device 500 FIG. 8 shows a schematic configuration diagram of an embodiment of the plate unloading device 500. In the figure, parts having the same functions as in FIGS. 2 and 3 are given the same reference numerals. The play l-unloading device t500 includes a chute 18 that is tiltably provided at the bottom of a shooter frame 522, a cassette-type plate storage container 19, an unloading conveyor 20, an unloading guide plate 523, an extension lane 524, and an inclined lane 525
It consists of Among these, the plate of the first stamping system is conveyed onto the chute 18 by the first stamping conveyor 13 from the back side of the paper toward the front side (this direction corresponds to the direction of arrow X1 in FIG. The plates of the second stamping system are conveyed by the second stamping conveyor 14 from the front side of the paper to the back side (this direction corresponds to the direction of arrow X2 in FIG. It is held on the shooter 18. Then, when the amount of -vehicle body parts (one set) is collected, a one set completion signal is sent from the controller, and the /eta 18 is tilted by means not shown. This tilting of the chute 18 causes the plate 5 to be placed on the chute (
fall). On the other hand, a large number of partition plates 526 are housed in the plate storage container 19, and are transported in the traveling direction Y3 by the carry-out conveyor 20 to the chute frame body 52.
When passing through the lower gate 527 of No. 2, this partition plate 52
6 is knocked down by the lower gate 527 in the reverse traveling direction Y4. When the grate storage container 19 advances further and reaches the position (84 points shown in FIG. 3) where it receives the grate 5 falling from the chute 18, a frame feeder (not shown) provided on the bottom of the plate storage container 19 is opened. The light plate also operates a photosensor (not shown) to stop the discharge conveyor 20. At this time, the most advanced partition plate 526
The lower end of the sheet contacts a reversing guide 528 fixed to the conveyance guide plate 523. Due to this contact, this partition plate 52
6 is reversed in the advancing direction Y3, a V-shaped opening 529 is formed between it and the next partition plate 526, and the plate 5 is on standby in a state where it can be received. In this way, each time the chute 18 is tilted, the plate storage container 19 advances one pitch at a time in the traveling direction Y3 based on the detection of the drop of the plate by means not shown, and the partition plate 5
Each time, the plates 26 are reversed one by one in the traveling direction Y3 to form a V-shaped opening 529 for receiving the falling plates, and each time the plates 5 corresponding to the vehicle body (one set I/minute) are received.

In this way, when the last partition plate 526 is reversed by the reversal guide 528, the grate storage container 19
It is released from the carry-out conveyor 20.

After that, this plate storage container 19 is moved to the unloading guide plate 5.

Therefore, in order to reduce the number of plate storage containers that are kept waiting on the carry-out guide plate 523, it is preferable that the conveyance guide plate 523 be configured to be relatively short.Furthermore, the inclined lane 525 is Its tip is in contact with the rear end of the conveyor 20, and the empty grate storage container 19 before receiving the plate 5 is mounted on this inclined lane 525. Therefore, the empty plate storage container 19 is placed on the inclined lane 525. 525 slides onto the carry-out conveyor 20 due to its inclination in the traveling direction Y3.By the way, in this embodiment, about seven empty plate storage containers 19 can be mounted on the conveyor 20. The grate storage container 19 has about 20 partition plates 526 and can receive various plates for 20 car bodies.The inclined lane 525 is far away from the worker who is located in front of the unloading guide 523. , empty grate storage container 1
9 is difficult to replenish. The shooter frame 522 is provided with a switch 532 for raising and lowering the tilted lane, and by operating the switch 532 for raising and lowering the tilted lane, the tilted lane 525 is pulled into the state 525' having an inclination in the reverse traveling direction Y4.

When the plate storage container 19 is conveyed in the conveying direction Y3, the tongue-like protrusion 73
7 comes into contact with the reversing guide 528, the partition plate 526 is reversed from the reverse unloading direction Y4 to the unloading direction Y3, and as shown in FIG. An opening 529 is formed. By forming this opening 529, the plate 5 shot from the shooter 18 is easily accommodated between the partition plates 526. The width of the partition plate 5260 is smaller than the width of the plate 50, making it easier to take out the plate 5.

[Effects of the Invention] As described above, according to the present invention, two laser heads are arranged in parallel, two hopper sections each housing various plates are provided so as to be movable in the front and rear direction, After carrying in the required plates selected by the movement of the hopper section, and connecting one end of two stamping conveyors to be engraved by the laser bed to each of the hopper sections, and collecting the engraved plates. By connecting the carrying out conveyor to the other end of the stamping conveyor facing each other, normal 1+1 operation is possible, marking time is shortened, and independent operation is also possible.
The stamping systems of each set back up each other to maintain their operating efficiency, and the engraved plates are collected for each car body (one set) and transported out continuously, which improves work efficiency. It is played.
